FILTER-IT is a biological product specially formulated to rapidly establish full biological activity in pond filters.

FILTER-IT consists of a selected range of bacteria and other important micro-organisms that are critical to the effective function of aquatic bio-filters. Once introduced into the water circulating through the bio-filter the micro-organisms quickly become established in the filter where they grow and multiply to provide an effective method of removing waste materials from the water, which would otherwise accumulate and could be poisonous to fish.
